To all whom it may concern." ,y

Be it known that I, Josnrrr MALONYAY, a citizen of the .Kingdomnof Hungary, and resident of Debrecen, in the county of Hajdu and Kingdom of Hungary, have invented certain new and useful ImproVements in Power-Operated Plows or Other Agricultural Implements, of which the following is a specification. p v

The invention relates to power operated plows orother agricultural implements on the single machine system without anchoring devices. According to the invention the outward or idle draught and the inward or working draught are both efl'ected bythe" machine; and

ties. When the plow reaches the end of its idle draughta signal must be given to stop or slow down the driving machine, in order that the drum for the working draught may be coupled up. If the drum on the driving machine is not released at the righttime at.

the end of the outwardfdraughtpthe plow does not stop exactly at the end of the field, which is dangerous if the fie'ldis bordered 3 end of the outward draughtwhen th'ewinding drum is beingreleased from the runn ng wheels, the driving machine still causes the drum 'to rotate for some revolutions and to wind on the rope. The drumon the plow,

however, winds on in the one draught only as much rope as is wound ofl'. on-the other draught and the excess quantity on the drum of the engine which is wound in the time between the stoppage of the plow and the release of the drum of the driving-machine is not taken up on the drum of the plow. These lengths of rope are constantly inthese known devices; the winding drum in the working draught is rotated by the run- 7 ning wheels which worksinefiiciently.

The arrangement according: to the inventionhas, besides'obviating the above drawshown an example according to the inven erating at different circumferential velociby a ditch or a line of trees, since the plough- 'man cannot bringtheplowtorest. At the the shaft H..the drum Ilbeing coupled'up creased in the successive draughts. Also,'in

backs, also the advantage that the rope need have only about half the cross section of the previously used main rope, andthe implementlcanbe brought to rest independently of the dr1vingmachineby the ploughman, the machine running duringbothdraughts at the same speed. Finally, the circumferential velocity of both drums can bethe same. I

A coupling Z serves to connect either drum to opposite'position f the drum II will be braked. The end K? of the rope which is fastened on this drum and passes over a pul-' .ley' 1 of the'plow A B is on the outward draught wound on the drum of the machine,

the end K of the rope being wound off the drum II. The pulley 1 whichis mounted loosely on a shaft 4 onthe frame of the plow i is rotated in the direction ofthe arrow by the rope K K 7 The rotation of the pulley gear 10, 13 or 11, .12.

1 is transmitted to the shaft 4. by a friction coupling 2 operated by a lever 3. On the shaft 4c are mounted loosely a sprocket wheel 5 and a spur wheel 6 which can be coupled alternately to the shaft 4 by pawl and ratchet Ifthe ratchet gear 11, '12 is coupled up the spur wheel 6 is rotated and with it a spur. wheel 8, differential drive D, shafts 14:, 15 and the running wheel, J J .and the plow. is moved away from the machine in its idle draught, While the pawl and ratchet gear 10, 13 slides idly. As soon as the. plow has reached the limits ofv the field the ploughman' stops the plow by releasing the friction coupling 2; the pulley 1, however. still rotating. The machinist effects the return movement of the plow by braking the drum II, which was previously rotating loosely, so that the'fope is not further unwound from the drum. Since, however, the drum I is still rotating and the rope woundup, the plow is drawn towards the machine.

Figs. 3, 4', 5 and 6 show details of the con structions shownin Figures 1' and 2,*on a larger scale. Fig. 3 shows the lever 3 in the same'position as in Fig.2, when the pulley 1 is coupled to the shaft 4: by means of the friction coupling 2. Fig. 4: shoWs the pulley 1 coupled from the shaft 4:, the pulley is loose on the shaft and may turn. The lever may be turned around the pin 17 provided on the plow-frame. When the lever 3 is in the position shown in Fig. 1, the signalling device 16 contacts with the pulley 1 by means of a small disc 16 whereby the disc is rotated by frictional contact with the rotating pulley, and thus the working of the device starts. The connection between the differential drive with the shaft 4: is shown in Figs. 5 and 6. The wheels 5 and 6' engage with the wheels"? and 8 as described above. Both wheels 7 and 8 are keyed to a sleeve 18, which is loose on the shafts 14 and 15. Both sleeves are connected through a casing19 which is cylindrical I at the center and conical at both ends.

differential drive composed of four bevel wheels is disposed within this casing. The

larger bevel wheels are keyed to the ends of the shafts 1a, 15, and are engaged by the smaller bevel wheels which are mountedon fixed bearings, oppositely arranged within the casing. With this arrangement the rotating wheel 7 or 8 rotates the sleeve com-' posed of parts 18 and 19 whereby the bevelwheels which rotate on thefixed bearings secured within thecasing, rotatethe one or the other of the shafts 14 and 1.5 bvmeans of the larger bevel wheel, j according to whether the toothed or the chain wheel on the shaft 4 is rotated by this shaft.

When the plow reaches the machine, the

rope, which on the outward draught was The unwound from the drum II, has been rewound on the drum I. g

If the plow is to be again moved outwards, the connection between the'drum I and, the shaft H is released by means of the cou- .pling Z and the drum II coupled with the the sprocket wheel 7, the differential-drive D andthe shafts 14, '15 to the running wheels J ,J i 7' In working draughts both ratchet "gears are out of action. In idle draughts'the running wheels in one direction of rotation of the pulley 1 are driven bya'sprocket wheel and in theother direction by-atoothed wheel; on the" idle draught the running wheels are always turned in the same direc tion'independently of the change of direction of the rope. v g V E E and E are the ploughshares and C is the leading wheel of the plow.
